Answer:
Approach: Difference of Squares Pattern
Step-by-step explanation:
The given binomial is:
We can rewrite to obtain:
This is a difference of two squares, so we will factor using difference of squares pattern.
Recall that:
If we let
and
Then we can factor the given binomial to obtain:
Candidate X won 63 out of the 100 "votes" of the poll participants.
So candidate X won 63% of the votes in the poll.
This means that candidate X is expected to win the elections by a percentage close to 63%.
63% of the voters is (63/100)*5000=63*50=3150 voters
Answer: 3150
Answer:
None
Step-by-step explanation:
Let c=cost of chicken and d=cost of duck; 50c+30d=550 and 44c+36d=532.
So 5c+3d=55, 11c+9d=133.
Therefore 15c+9d=165, subtracting 11c+9d=133 we get: 4c=32 so c=8.
5c+3d=40+3d=55, so 3d=15 and d=5.
Cost of chicken is $8 and cost of duck is $5.
